Befit rknown thatllf, RUJENlluorrrniz,` la citizen'of the UnitedStates, andja resident lof' `New York, county andfState of New t .,Yorlr, have invented a certain new and use-Y "fullmproveinent ini Floor-Poli`shing Devices, of which the following is a full, clear7 and exactspeciication.

f Fig.l 3 is a fragmentary view, Vpartlyin 'i to permit Vthe device" to "be conveniently proximity-'to' one endof the tank is a cap or other-suitable polishing liqufidinto Vthe supply chamberl in the tank, and through the underside `oit thetank contiguous to the other end thereof isan openingwhichserves as an outlet 14.1'The outlet lit leads into L 1: sub-chamber `15` which is provided by S01- dering or otherwise `scouring to the underfsid'e of the tank-10a curved, or substantially VfShapediQplate lextending longitudinally ofthe tank, and this plate is disposedV so that its apex is in spaced opposed relationto the underside of the tank and to its'outlt 14. g' i v`Atinteiwals through'the apex 'of the V- shaped plate-16 are a number of openings 17 -which serve as means for feeding'the liquid from the su`p`kf -chamber A15' to a rotatable fbufer,for roller 10'of feltor other absorbent yielding material which is wrapped around the rod 19is1of alength to extend soin'etilisi acore ofvwood or the like Lhaving a rod 19 Q- i .disposedf lengthwise therethrough. p The `butter-[18 ispreferably similar in length lto the tankand to'zthe V-shaped ,plate 16, and

the extreme 'ends of `the rod 19 are'two narrow'rollers, or buifers 20 and 21 which are slightly spaced from the buffer 18,` and these 'rollers are also made ofthe same material as thelarger buffer. The partsoftherod 19 lbetweenfthe buffer 18 and the rollers 20 and 21 arerevolublyyheldin the lower ends of ibrackets'f); and 24'both of which have their other endssecured to the endsy of the` tankfin 50 A be'suitably adjusted to regulate the feed of 55 f cap ofthe inlet is removed therefrom, `and i V-sh'aped plate 16 so that liquid fed through the openings 17 from the sub-chamber 15 posed incloseproximity tothe apex of the will'be receivedthereon.

Serving to permit the supply of the liquidl from the chamber 13 to the subchamber 15 to be regulated, a spring actuated feed controller, or valve, as 24, is provided. The

feeder, orvalve 24 has fa rod 25 movably disposedthrough the outlet 14 of the'tank 10- and through an opening in theupper part thereof, and this rod is adapted to be directed in upward and downward directions as well as being rotatable.` Oneend of the rod 25 extends into the sub-chamber 15 while its other end extends above the tank, and vontlie lower end of the rod 25 is provided a disk 26 adapted to be guided to and from the underside oi' thetank forclosing andV opening the outlet-14 of Vthe-,supply chamber 13. l ,l Tothe rod-2 5 under the disk 26 is movably l held one end* of arspring, as 27,;having its other end'seoured to the wallof the tank,

andgthis spring normally serves toforce the rod .and lthe disk in a direction" to close the outlet 14. On the upper end of the. rod 2 5 is tightly'held one :end of a bar28 which eX? tends in a lateral direction `withrespect to the rod, and the central part of one edge ofthebar isnotchedpat 29.1 Encircling the rod 25, and'between the;` wall of.- the tank and the barl 28, is a spiral `spring 30 which also. normallyserves to force the rod upwardly so that its disk will be seated over the outlet 14. Inorder to hold the valveA 24 for keeping the outlet 14 of the tank open foi- ,asuitable length of timethe rod 25 is forced in aidownwardly .direction by press-- ing the arm 28 valso downwardly. The arm 28is then rotatably moved so that it will be directed under the head of a `threaded bolt 31 which is screwed in a threaded opening providedinthe wall of thetank. The bolt 31 willv thereby enter the notch 29 of the arm 28, and the valve 24 willbe heldin open position from the outlet 14 to permit liquid in the supply chamber 13 tozbe fed to the sub-chamber'l. By also adjusting the bolt 31 in the walloil the tank the valvewill g; the liquid to meet desired requirementsig n; j Tooperate the device a suiiicient quantityV .,ogoil, or other polishing liquid is poured through the inlet 12 of the tank 10 after the I the valve 24 operated to close the outlet 14 of the tank. The outlet 14 isthen opened by adjusting the valve 24, as above described, `for permitting a required quantity oftheliquid to be ed-'romthe supply chamber 13 to the subfchamber 15.4 B y directing the device through the "medium-of;

thehandle 10 so that the rollers 18, 20,421

willvbe revolved contact with the floor 'of a building, `ory otherstructuref,l`or surface, the liquid in the' sub-chamber 15 will 'be delivered to the roller 18v .which in turn will distribute the liquid evenly" on the sur-face,

and by the use of-the'two narrow rioll'erstex.- tending a distance `from the ends of the tank 'the device may be so manipulated that'the corners of theloorof a room may be pro'perly oiled. When it is desired vvto polish 'v the surfaceafter. the liquid is applied thereon, the buffer, or roller 18 is held against rotation by providing a" brake, as 32. The brake 32 is in the form cfa substantially L- shaped plate -to providetwov angularlyl disposed arms 33"'and34 which are nearly the,`

.same lengths aslthe tank 10.` The uplperg edge of the arm 34 of the brake ishinged, at

35, longitudinally to the tank 10 ina manner whereby the arm 33 will snugly .engage the roller 18 whenv the lbrakeisfswung towardthe apex of they-shaped plate-'116v kof the tank. 'lherollerl'A will thenbeheld l against rotation, andby moving :theidevice therewith it will be readily polished. By

`toand fro, over-the surface kand in contact f p swinging the brake 32 in a reverse direction the roller-18 will Vvbereleased from its env gagement therewith. f so that. the device may.
